Površinsko hrapavljenje, rast dendrita i nastajanje prahova pri elektrohemijskom taloženju metala / The surface roughness amplification, dendritic growth and powders formation in electrodeposition of metals
(Универзитет у Београду, Технолошко-металуршки факултет, 1982)

Photoelectrochemical microscopy of oxide films on metals: Ti/TiO2 interface
(Elsevier, 1988)
Thin electrochemically grown oxide films on polycrystalline titanium substrates were examined by photoelectrochemical and electron diffraction techniques. Photoelectrochemical microscopy, based on illumination by a focused ...
Electrocatalysis of oxygen on single crystal gold electrodes
(Elsevier, 1989)
Oxide formation and oxygen reduction on gold have been investigated with single crystal electrode surfaces of various orientations. Both reactions show sensitivity to the surface orientation, presence of steps, their density ...
The surface structure of RuO2: A leed, auger and XPS study of the (110) and (100) faces
(Elsevier, 1988)
The (110) and the (100) surfaces of RuO2 show well defined LEED patterns. The surface lattice dimensions agree within 5% with the values predicted from X-ray diffraction. Both surfaces undergo a series of reversible surface ...
Oxygen reduction on a ruthenium electrode in acid electrolytes
(Elsevier, 1986)
The kinetics and mechanism of O2 reduction on an Ru electrode in acid electrolytes have been measured by using a disc—ring method. The reaction proceeds through a “parallel” mechanism with the exchange of approximately ...
Two-dimensional electrocrystallization of thallium oxide on the single crystal gold surfaces
(Elsevier, 1984)
The electrocrystallization of thin anodic films on metal electrodes continues
provoke interest since the original work of Bewick et al. [1]. These
studies have been focused on the film formation on mercury [1--3] ...
Synergetic electrocatalytic effect of d metals for the hydrogen evolution reaction on gold substrates
(Elsevier, 1984)
An electrocatalytic method developed previously for the depolarization of the hydrogen evolution reaction (HER) on graphite, iron, steel, nickel and titanium substrate surfaces was employed to improve the polarization ...
Lanthanum-molybdenum coating for hydrogen evolution on titanium
(Switzerland : Springer Nature, 1984)
There is practical interest in the use of titanium as a cathode material in brine electrolysis processes. The overvoltage of hydrogen evolution on titanium is, however, very high and, at the same time, hydrogen penetrates ...
Multistage alkaline permanganate degradation of a type II kerogen
(Elsevier, 1984)
The products of a 27-step alkaline permanganate degradation of a type II kerogen from a sample of Toarcian shale, Paris Basin, have been studied. The high yield of oxidation products consisted of 1.86% neutrals and bases, ...
Mass-spectrometric analysis of the products formed in a D.C. Arc Plasma / Massenspektrometrische Analyse der im Gleichstrombogen-Plasma gebildeten Produkte
(Springer Nature, 1980)
The carbon content was determined in the plasma of horizontal electric arc discharging between carbon electrodes in a) a graphite tube and b) a ceramic tube, in the presence of an inhomogeneous magnetic field. After 20 s ...
